In this way, migration of autoreactive T-cells and antigen expression, expression of adhesion molecules, secretion of matrix metalloproteinases, Fc expression in macrophages and major histocompatibility complex-2 expression in macrophages and microglia are suppressed (11).
By binding BLyS, Benlysta inhibits the survival of B cells, including autoreactive B cells, and reduces the differentiation of B cells into immunoglobulin-producing plasma cells, revealed the company.
Less than 1000 B-cells are autoreactive. So, to find them, the researchers designed a method to identify and isolate the population.
Other immunologists believe special autoreactive B-cell receptors trigger the formation of B1 cells.
Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease predominantly affecting women, and its clinical features always include hematological abnormalities, skin and joint diseases, renal disease, and neuropsychiatric complications.[1],[2] SLE is characterized by the development of dysregulated autoreactive B-cell-derived autoantibodies directed against nuclear and cellular components and the activation of complex inflammatory cascades, thereby resulting in multisystem organ damage.[1],[2]

This highlights the fact that deletion of T cells by thymic selection is not 100% and that autoreactive T cells escape the selection process.
